Sodium hydrogen carbonate (NaHCO,), also known as sodium bicarbonate or "baking soda", can be used to relieve acid indigestion. Acid indigestion is the burning sensation you get in your stomach when it contains too much hydrochloric acid (HCl) , which the stomach secretes to help digest food. Drinking a glass of water containing dissolved NaHCO, neutralizes excess HCl through this reaction: HCl(aq) + NaHCO3(aq) → NaCl(aq) + H2O(1) + Co,(g) The CO, gas produced is what makes you burp after drinking the solution. Suppose the fluid in the stomach of a man suffering from indigestion can be considered to be 250. mL of a 0.088 M HCl solution. What mass of NaHCO, would he need to ingest to neutralize this much HCl ? Be sure your answer has the correct number of significant digits.

Codeine, C18H26O3N is the active ingredient in the sedative Paregoric™ and is a weak Brønsted base with Kb = 8.9 x 10–7 (conjugate acid is C18H26O3NH+). To a 20.00 mL sample of 0.0155 M aqueous solution of Codeine is added 9.75 mL of 0.0180 M HCl(aq). a) Calculate the pH of the above solution. b) To the above solution is added 1.00 mL of 0.0150 M NaOH(aq). Calculate the new pH that results and the % change in pH. Show your work and justify any approximations made.

One method for chemical analysis involves finding a reactant that will precipitate the species of interest, but not the other species. The mass of the precipitate is then used to determine the mass of the species of interest present in the original sample. For example, calcium ions can be precipitated from an aqueous solution by adding of sodium oxalate Na2C2O4. The balanced equation is: Ca2+(aq) + Na2C2O4 (aq) --> CaC2O4 (s) + 2 Na+ (aq) Suppose you had a solution with approximately 15.0 g of calcium ions. Show by calculation whether the addition of 15.0 g of sodium oxalate will precipitate all of the calcium ions present in the sample.
